1. Background

   A vulnerability in certain versions of the Java(TM) Runtime Environment 
   may allow malicious Java code to execute unauthorized commands. However, 
   permission to execute at least one command must have been granted in order 
   for this vulnerability to be exploited. Since no permission is granted 
   by default, the circumstances necessary to exploit this vulnerability 
   are relatively rare. In the Java Development Kit 1.1.x (JDK(TM) 1.1.x) 
   (browsers included), an applet must be signed to have execute permission 
   (signed applets may execute anything in JDK 1.1.x.) 

   This issue may or may not affect other vendors' Java technology
   implementations which are derived from Sun's JDK source base. 
   Sun has notified and made the remedy available to its Java licensees.
    
   To the best of Sun's knowledge, Netscape Navigator(TM) and Microsoft 
   Internet Explorer are not exposed to this vulnerability.

   Sun recommends that you upgrade to the latest JDK and JRE releases 
   listed in section 3 of this bulletin.
   
   
2. Affected Releases
   
   The following releases are affected:

     JDK and JRE 1.1.8_003 or earlier
     JDK and JRE 1.1.7B_005 or earlier
     JDK and JRE 1.1.6_007 or earlier

   and 1.1.6 should no longer be used. In addition, releases prior to 
   JDK and JRE 1.1.6 for Windows or Solaris should no longer be used. 
   Users of these releases should upgrade to a later release listed in
